Yolande de Polastron
–
She was considered one of the great beauties of pre-Revolutionary society, but her extravagance and exclusivity earned her many enemies. Yolande Martine Gabrielle de Polastron was born in Paris in the reign of King Louis XV and her parents were Jean François Gabriel, Count of Polastron, seigneur de Noueilles, Venerque and Grépiac, and Jeanne Charlotte Hérault de Vaucresson. As was customary with aristocrats, most of whom more than one Christian name. While Gabrielle was still an infant, her parents moved to the family Château of Noueilles, when Gabrielle was three, her mother died and her welfare was entrusted to an aunt, who arranged for her to receive a convent education. At the age of 16, Gabrielle was betrothed to Jules François Armand, comte de Polignac, marquis de Mancini, whom she married on 7 July 1767, polignacs family had a well-bred ancestry similar to Gabrielles family, and was in equally uncomfortable financial straits. At the time of his marriage, Polignac was serving in the Régiment de Royal Dragons, within a few years of the marriage, Jules and Gabrielle had two children, a daughter Aglaé and a son. Two more sons followed several years later, including Jules, prince de Polignac who became the minister of France in 1829. Most surviving portraits show her to be pretty, one historian said that Gabrielle, in her portraits by Louise Élisabeth Vigée Le Brun, generally looks like some harvested and luscious fruit. She had dark hair, very pale white skin and, perhaps most unusually. Compiling the contemporary accounts of her, one historian has summarised her physical appearance thus. With her cloud of dark hair, her big eyes, her neat nose, the cost of maintaining oneself at the court of Versailles was ruinous and Gabrielle replied that her husband did not have the money to finance a permanent move to the palace. Determined to keep her new favourite by her side, the Queen agreed to settle the many outstanding debts. She was, however, resented by other members of the entourage, particularly the Queens confessor and her chief political adviser. Charismatic and beautiful, Gabrielle became the leader of the Queens exclusive circle. She was considered by many of her friends to be elegant, sophisticated, in 1780, her husband was given the title of duc de Polignac, thus making her duchesse, a further source of irritation to the courtiers. By the late 1780s, thousands of pornographic pamphlets alleged that Gabrielle was the Queens lesbian lover and those who were not themselves swept into the whirlpool, stood at the marge contemplating it with astonishment. The Queens hand was guided by the violet-eyed, the lovely. In 1782, the Governess to the Children of France, Victoire de Rohan, princesse de Guéméné, the Queen replaced the princess with Gabrielle
